Summary: 1. main objective : to assess the consequences of a maternal hyperthyroïd during pregnancy on intellectual development of the child from 6 to 9 years 2. secondary objectives : 1. to assess the consequences of a maternal hyperthyroïd during pregnancy on the capacities of attention, learning process and the degree of hyperactivity of the child from 6 to 9 years. 2. to study if it exist differences of intellectual development, capacities of attention, learning process, and degree of hyperactivity in the child from 6 to 9 years, born to hyperthyroid mother during pregnancy, according to: * the etiology of the maternal hyperthyroïd (transitory gestation hyperthyroid versus disease of basedow), * the use or not of a anti-thyroid treatment, * the rate of tsh néonatal (measured with the blotter by tracking with j3 at all the new born ones).

1. inclusion criteria : * old from 6 to 9 years included * age of gestation between ≥37 and \<41 weeks of amenorrhoea * born from a mono-foetale pregnancy * euthyroïd at the time of the entry in the study * provided education for at the elementary school on a level adapted to its age 2. non inclusion criteria : * presenting a congenital hypothyroïd or a known thyroid dysfonction at the time of the entry in the study * carrier of a chronic pathology (organic or psychological) or malformative severe * presenting an antecedent of deficit of the attention-hyperactivity to the 1st degree 3. exclusion criteria : o discovered of a thyroid dysfonction at the time of the entry in the study 4. strategies / procedures : multicentric, comparative study of a troop of child born to hyperthyroïd mothers during pregnancy (children exposed to the maternal hyperthyroïd) and children born to euthyroïd mothers during pregnancy (nonexposed children with the maternal hyperthyroïd). * 1st part of the study: retrospective analyze of the files of symptomatic hyperthyroid mothers during pregnancy. * 2nd part of the study: assessment of intellectual development, capacities of attention, learning process and degree of hyperactivity of the children between 6 and 9 years. the exposed children (born to hyperthyroïd mothers during pregnancy) will be compared with nonexposed children (born to euthyroïd mothers during pregnancy).
